7 Claims. (Cl. 206-4531) ABSTRACT OF THE DISCLOSURE A display cartonhaving a curved transparent display surface provided by shortened topand front panels interconnected by end panels with an arcuate upper edgewhich may be overwrapped with a heat shrunk thermoplastic film.

This invention relates to a display carton. In one aspect the inventionrelates to a display carton having an arcuate transparent window.

It is an object of the invention to provide a display carton. Stillanother object is to produce a package with means to resiliently supportthe product to reduce breakage.

Yet another object of the invention is to provide a package that may beconveniently and compactly folded when not in use.

Still another object is to provide a display carton particularlysuitable for overwrapping with a heat shiukable film These and otherobjects of the invention will be readily apparent to those skilled inthe art from the following disclosure, appended drawing and claims.

The display carton of this invention has a number of advantages over theusual display cartons having an open top. By employing this new carton,a pacakge is provided which has greater rigidity to withstand the shrinkforces of a heat shrinkable film, ability to stack, greater productvisibility when stacked and better product protection.

FIGURE 1 is a perspective view of the display carton 2 of the inventionwith a transparent film.

FIGURE 2 is a perspective view of a carton 3 suitable for theconstruction of a display carton.

FIGURE 1 illustrates one embodiment of the invention for a displaycarton 2 and includes a bottom panel, back panel, front panel 6 and toppanel 12 hinged to each other, in series, along with end panels suitablyhinged and locked to provide a carton. Preferably the carton 2 is anelongated hexahedral as illustrated but may also include a variety ofshapes and ratios of length, width and heights. Preferably, the toppanel and front panel 6 have resilient flaps 14 and 4 hingedly connectedthereto which are folded inwardly to provide resilient support for anyproduct contained therein. A suitable product, such as wafer 48, isinserted into the container with the support flaps 14 and 4 firmlysupporting the Wafers. The front panel 6 and top panel 12 are narrowthus leaving a display area and so as to provide access to the interiorof the package when the film 50 is removed. Since the upper edges of therespective end panels are arcuate, this provides, in combination with aheat shrinkable film 50, a curved transparent display surface shaped toclosely follow the arcuate contours of the wafer thus improving theoverall appearance of the Product and package.

FIGURE 2 represents a suitable blank 3 for the construction of thecarton and comprises a rectangular blank of cardboard or the like whichmay be elongated or substantially of equal length and width. The blank 3is prescored (represented by the dotted lines in FIGURE 2) so as to formhinged, connecting, elongated panels comprising, in series, a front flappanel 4, a front panel 6, a bottom panel 8, a back panel 10, a top panel12, and a top 3,332,545 Patented July 25, 1967 flap panel 14. The toppanel 12 is preferably of substantially less Width than said bottompanel and said front panel is preferably of substantially less width ofsaid back panel so as to provide a display opening as hereinbeforediscussed. End panels 16, 18, 20, 22, 24, 26, 28, and 30, which extendlaterally from the ends of the front, bottom, back, and top panels, arepre-scored and thus hingedly connected so that upon being foldedtogether, the panels interlock and provide a closed carton. A first pairof end panels 16 and 18, having one end panel hinged to each end of thefront panel but having substantially greater width than said frontpanel, has arcuate edges extending from an intermediate portion of theupper edge thereof to the point of contact (42 and 40) with the upperedge of said front panel 6. A second pair of end panels 24 and 26 isprovided with an end panel hinged to each end of the back panel 10, saidend panels 24 and 26 being arcuate from an intermediate portion of theoutside edge thereof to an intermediate portion of the bottom edge ofsaid back panel 10. These end panels (connected to the front and backpanels) are folded inwardly to enclose the product and are interiorlypositioned by interlocking end panels 16, 18 and 24 and 26. A third pairof interlocking panels 20' and 22, which extend laterally from each endof the bottom panel 8, are provided with interlocking slits 36 and 38extending from the top edge to the center portion of the end panel. Afourth pair of end panels 28 and 30 extends laterally from each end ofthe top panel with the overall width of the end panels beingsubstantially equal to the combined width of the top panel 12 and topflap panel 14. This fourth pair of end panels has edges arcuate from theintermediate portion of the respective bottom edge to the lowermostpoint of contact (44 and 46) with the top panel. These end panels 28 and30 also have slits 34 and 32 so as to provide for interlocking betweenthe respective third and fourth pairs of interlocking end panels.Preferably, a portion of the upper outer quadrant of these interlockingpanels is cut away to provide ease of interlocking. A neater package ispossible by slashing the top fiap 14 at the upper edges to permit thepoints of contact (44 and 46) to be slightly inward of the edge of thetop flap.

Preferably, the resultant carton is overwrapped with a transparent film.Particularly useful as Wrappings are the preferred heat shrinkablefilms, such as the biaxially oriented, irradiated polyethylene filmsdescribed in patents issued to Baird et al., US. 3,022,543 and Rainer etal., US. 2,877,500. Any suitable transparent film (including laminates)may be employed including the Sarans (vinylidene chloride andvinylchloride copolymers), polyethylene, polypropylene and the like.Preferably, the film is 0.1 to 20' mils thick.

.While certain structures and process steps have been described forpurposes of illustration, the invention is not limited to these.Variation and modification within the scope of the disclosure and theclaims can readily be July 25, 1967 F.
